    With its different activities (website, database, Design Guide, annual workshop Textile Roofs and TensiNews) TensiNet has an impact at both the educational and professional level. Initially, specific information was scattered and retained by experts. However, the networking that has been initiated reachesbeyond the partners and has an impact on knowledge and procedures in institutions as well as professional organisations and businesses. TensiNet creates a forum, an association and a reference point.

  • Umbrellas for the Chamber of Commerce,

    Wrzburg In the inner courtyard of the Chamber of Commerce at Wrzburgthree extraordinary umbrellas were installed, offering an impressivesight. Each umbrella has a height of approximately 13 m and the totalcovered area is approximately 475 m2. The biggest umbrella has anedge length of 14 m x 14 m. The funnel shape, which often is used indesert areas to collect rain, also has the advantage that it can drainthe surface rain via the posts, thus avoiding costly drainage systems.

    The main sub-structure of the roof consists of clamped steel postsand a fine frame fixed on the posts by horizontal and sloped struts.The extremely demanding tensioning process of the posts was carriedout via the top plate into the ceiling of the underground parking spacedirectly beneath.

    Due to the use of ETFE-foil for these umbrellas their appearance isvery filigree and light. A cable-net integrated in the ETFE-foilstransmits the external loading to the frame and post.

    For an election campaign aninnovative, expressive andmobile booth was needed for aparty as an alternative for thenormally used umbrellas andtables. The pneumatic boothfulfils all the requirements: it ismobile and light, expressive andconvertible. On the top of analuminium mast with anintegrated round table themembrane is connected over akind of hub. At the top of thishub the ventilator is located.Inside the mast are the electricalcables and the rainwaterdrainage. The foot of the boothis a standard footing for marketumbrellas. The whole boothcan be demounted within

    5 minutes into manageablepieces, transportable in a smallcar or by hand.This inflating pneumaticbubble is an eye-catcher andan attraction. In less than 2 minutes the pneumaticstructure is totally inflated by asolar powered ventilator. The ventilator is regulated by atwo-step switch, which reducedthe air volume after the bubbleis totally inflated. The high translucency of themembrane material allows thepneumatic balloon to glowunder the influence of brightsunlight. For use during thenight appropriate lighting canbe installed inside.

    A mobile tent structure forms anelegant and charming cover forthe existing grandstand of theScherenburgfestspiele inGmnden above the River Main.A light translucent membraneroof provides shelter from windand rain for the spectatorsduring the theatre summerfestival without destroying theopen air athmosphere that thisplace is well known for. Andbeing well integrated with thehistorical red sandstone ruins ofthe old castle this white strechedtextile roof creates anarchitecturally unique situationfor the theatre play. Also, itsattractive silhouette forms thenew symbol for thesummerfestival, that can be seenfrom far out in the valley.

    One interesting aspect of thisproject is the first officialapplication of the TensinetDesign Guide as a technicalreference for the engineering andthe approval procedure of thistent structure with the TV,which is the authorizedassociation for technicalsupervision in Germany.

    The membrane roof issupported by two internallylocated lattice masts (10.5mheight), which were positionedwithin the existing grandstand atthe edge of the upper stairways.The position and the form ofthe lattice mast provide acomfortable and safe situationfor the movement of the publicand also create the minimumdisturbance for the visibility ofthe spectators. Each one ofthese main masts supports twolattice outrigger beams. Thisoutrigger system provides theroof with structuralindependence regarding theadjacent historical building andallows the great span towardsthe stage. The lattice steelstructures also provide new well-positioned supports fortechnical illuminationequipment.

    For the membrane itself aTenera 3T20 fabric is used. Thisis a 100% Fluorpolyme
